The equipment you need

  • your ICO
  • a bottle of still mineral water with pH indication
  • a bowl or dish

Steps for carrying out the mineral water test

You can carry out a self-test at home right now using these simple tools 6 steps :

1) Remove the ICO from your Pool/Spa, remove the lower part of the ICO and rinse the ICO probes with tap water.

2) Wipe the ICO probes after rinsing with a soft cloth.

3) Pour the mineral water into the bowl or dish.

Warning: mineral water oxidises when opened, so the water test should be carried out immediately after opening. Otherwise, the pH will tend to rise above the value indicated on your bottle.

4) Immerse ICO in the bowl (the probes must be submerged).

5) Restart ICO with the application (check that Bluetooth is connected). Leave ICO in the water for approximately 2 hours.

6) Check that the measurements correspond to the values on the label of your bottle of mineral water.

  • You notice a difference between 0.00 and 0.3?  ? Your pH sensors works perfectly. You can simply modify target values in your app to reflect this possible differential.
  • Beyond a difference of +1, replace your probe
